Merwin Heating & Cooling - Mayville's Best HVAC Services

In our Wisconsin climate, heat pumps can freeze due to low refrigerant, airflow issues, or a faulty defrost cycle. Our technicians at Merwin Heating & Cooling will diagnose the specific cause—whether it's a leak, a dirty filter, or a component failure—and perform the necessary repair to restore proper operation and prevent future freeze-ups.

A dirty condenser coil, often clogged with pollen or debris common here, forces your AC to work harder, reducing cooling power and increasing energy bills. Merwin Heating & Cooling provides thorough professional coil cleaning as part of our maintenance services to restore efficiency, improve performance, and extend the life of your system.

To prevent problems like frozen components and dirty coils, we recommend seasonal maintenance visits. In spring, we'll clean and inspect your cooling system; in fall, we'll service your heating system. This proactive care from Merwin Heating & Cooling catches small issues early, ensuring reliable performance through our local winters and summers.
